How can I become the owner of a file that origins from another pc / user?

Command line instructions:

Use the chown command.

Example:

sudo chown user file

Where user is the username on the second pc. This needs to be run from the second pc.

GUI instructions:

Run Nautilus with sudo privileges

• Alt+F2
• Enter gksu nautilus.

• Enter your password.

• Now you can right-click on a file, go to the Permissions tab and select the new owner from the Owner combobox.
